title: 1-(5-Bromo-2-oxoindolin-3-yl-idene)thio-semicarbazone.
abstract: The title mol-ecule, C9H7BrN4OS, is essentially planar [r.m.s. deviation = 0.066 (2) Å], the maximum deviation from the mean plane through the non-H atoms being 0.190 (3) Å for the terminal amine N atom. In the crystal, mol-ecules are linked through N-H⋯O and N-H⋯S inter-actions, generating infinite chains along the b-axis direction. In turn, the chains are stacked along the a axis via π-π inter-actions [centroid-centroid distance = 3.470 (2) Å] and further connected by N-H⋯Br inter-actions into a three-dimensional network. An intra-molecular N-H⋯O hydrogen bond is also observed.
